            Bug ID: 308428
          Severity: major
           Version: 4.8.5
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: Cannot see external monitor / projector
    Classification: Unclassified
                OS: Linux
          Reporter: elmar.roberg at gmail.com
          Hardware: Debian stable
            Status: UNCONFIRMED
         Component: general
           Product: systemsettings

Prefer to not use Nvidia drivers because is too hard to configure. Do not
understand what I am doing. When you are on the spot in a presentation, it hard
to manipulate the nvidia options.
There needs to be a low level override that simply duplicates laptop display
onto a projector.
It is almost impossible to say what the make and model of the target projector
is before the time, thus one is faced with doing this set up minutes before it
is required. For anyone who speaks at conferences, uses a projector at meetings
or training sessions, and so on this is not only embarrassing but a show
stopper given that there is no time to fiddle with settings.
I never had this problem when I was using Ubuntu 11.04, but have hit a wall
with Kubuntu 12.04.

Reproducible: Always

Steps to Reproduce:
1. connect external projector
2. open system settings
3. select displays & monitors
4. choose "unify outputs"
Actual Results:  
Kubuntu does not "see" the projector, or (happened once) the projector displays
at incorrect resolution, flashes display / no connection, until it gives up.
CPU runs at 100%.

Expected Results:  
adjust laptop display to resolution of projector (external display) seamlessly.
Show simultaneously on laptop display and projector.

Ideally, there should be an applet that can be used to force display
management, to use if all else fails. Even if one inputs the target resolution
and then forces the laptop display to mimic it.
